The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention. It is to be understood, however, that variations in such description may be adopted within the scope of the invention as set forth in the claims.

2,812,873 Patented Nov. 12, 1957 Figure 11 is a fragmentary cross-sectional view taken substantially on the plane of line 11 11 of Figure 9'.
The load transporting and handling machine of the present invention consists briefly dfa vehicle chassis 12, a load supporting bed 13 mounted on the chassis for rotation in a substantially horizontal plane and about a vertical axis for positioning articles such as containers 14 and 15 on the bed at selectable locations widthwise and longitudinal of thev chassis, and means 17 for raising and lowering the bed on the chassis. Preferably the bed 13 is carried by a subframe 18 which is mounted on the chassis forv raising and lowering relative thereto and which, in turn, supports the bed 13 for rotation about a verticalaxis substantially centrally of the widthwise dimension of the chassis. Also cooperating in the combination, the containers 14 and 15 are carried on the bed and may be reversibly. positioned upon appropriate rotation of the bed to relatively fore and aft positions with respect to the chassis, and are provided with ground engaging means 21 positioned for spanning of the widthwise dimension of the chassis and subframe and bed, and extendable to ground engaging position in the raised position of the bed, as depicted in Figure 3, for delivery of the rearmost container 15.
The machine of the present invention may be incorporated in various types of vehicles, such as automotive trucks and trailers. An automotive truck is here shown, having a chassis including ground engaging wheels 23 and a chassis frame 24, including spaced longitudinal frame rails 26 and 27, and carried by the wheels by means of a conventional spring structure 28. I
The subframe 18 here includes a pair of longitudinal frame members 30 and 31 which, for convenience in raising and lowering of the subframe andsuperimposed bed 13, are here pivotally mounted on the chassis at the relatively forwardly disposed ends 32 and 33 of the subframe for raising and lowering of the rearwardly disposed ends 34 and 35 of the subframe. Of course, as will be understood, other supported structures may be employed for the subframe to effect its relative raising and lowering with respect to the chassis. However, in the operations of the present machine it is most essential that the rearwardly disposed end of the bed 13 be raised and lowered and accordingly it is convenient to pivot the forwardly disposed ends 32 and 33 of the subframe as suggested. As here shown, such ends are secured by a transverse pivot pin 37 to brackets 38 and 39 secured to the rails 26 and 27 of the chassis frame. p The means 17 for raising and lowering of the subframe 18 is preferably manually controlled and here consists of a hydraulic jack mounted between the chassis and subframe. With reference to Figures 8, 9 and 10, it will'be seen that the housing or cylinder 41 of the actuator 17.is pivotally secured to the central portion .42 of a U-shaped bracket 43 having its upper ends 44 and 45 fastened to the frame rails 26 and 27. The piston or ram part 47 of the actuator is provided with a clevis bracket 48 pivotally secured to a strap 49 fixed to a rear cross-member 51 of the subframe 18. Energizing of the actuator 17 for raising and lowering of the subframe may be effected by manually operated or manually controlled power-operated pump means. The former is quite satisfactory for most applications and, as here shown, a hand-operated pump 53 is mounted on the side of the vehicle as seen in Figures 2 and 3, and is operatively connected by conduit 54 to the hydraulic cylinder 17.
Forming part of the subframe, directly below and supporting the bed 13 is a polygonal frame structure 56, "here of octagonal form, including spaced parallel polygonal sides 57, 58, 59, 60, 61, 62, 63 and 64. Wheels, 66, 67, 68, 69, 70, 71, 72 and 73 are mounted between each pair 9f polygonal sides on horizontal radially dis'posed axles carried by such sides for rotation of the wheels in vertical planes parallel to the sides. The subframe is also provided with a centrally disposed vertical spindle 76 carried by radialsupporting members 77 to provide a central bearing means for a depending tubular bearing 78 carried by and depending from a flat bottom plate 79 of the bed 13, the bottom 79 thus being supported on the wheels 66-73 for rotation in a horizontal plane.
In the present showing and as an important feature of the present construction, the containers 14 and 15 are demountably carried by the rotating bed 13 for picking up and delivering by the machine, and are accordingly preferably of the re-usable or refillable type for handling of various materials, liquid or dry, wherever the use of this type of container is feasible on an exchange basis. As here shown, the containers 14 and 15.are in the form of elongated cylindrical tanks as customarily used for storage and dispensing of gases or liquids such as fuel, fertilizers and the like. For example, the machine of the present invention is well adapted for handling the delivery of tanks containing aqua ammonia where full tanks may be transported to a desired point of use, as alongside a ditch or the like, into which the fertilizer may be dispensed, and the machine is likewise adapted for picking up the containers when emptied of their contents and returning them for refilling and re-use. To accommodate the demountable support for such tanks, the bed 13 is here provided with elongated saddle means 81 and 82 which provide spaced elongated upper concave surfaces for receiving and nesting the bottom of the tanks 14 and 15, thereby locating the latter in side by side position as illustrated. As will be observed from Figure 1, the tanks 14 and 15 are preferably formed with a lengthwise dimension greater than the widthwise dimensions of the chassis, subframe and bed, so that the opposite ends 83 and 84 of tank 14, and similarly the opposite ends 85 and 86 of tank 15, will overhang the full transverse dimensions of the vehicle, including the wheels 23, when the tanks are arranged in transversely extending position, as seen in Figure 1. Accordingly the depending ground engaging means 21 carried by the containers 14 and 15 may be let down vertically and into engagement with the ground while completely spanning the widthwise dimension of the vehicle. As here shown, such means consists of a pair of vertically movable legs 87 and 88 mounted on the container end wall 83, and similar legs 89 and 90 on end wall 84, and legs 91 and 92 on end wall 85, and legs 93 and 94 on end wall 86. As will be observed from the drawings, each of the end walls 8386 are provided with horizontally spaced generally vertically extending sleeves 96 which slidably carry for vertical reciprocation the legs 8794. The sleeves 96 may be angularly positioned on the end walls of the containers so as to cause the legs 87-94 to diverge downwardly to increase the lateral extent of the underlying support provided by the base ends of the legs. The latter are preferably provided with widened feet 97 for improving their ground support. Securing of the sleeves and legs in selected vertical positions of the legs may be effected by pins 98 carried by the sleeves and engageable through longitudinally spaced openings 99 in the legs.
The combination of members and parts as above described provides a variety of highly effective material handling operations, some of which are indicated in Figures l to 7 of the drawing. In normal operation, full tanks 14 and 15 to be delivered may be mounted on the truck, as illustrated in Figure lthat is, with the bed 13 rotated to a transverse position of the tanks. Latch means is preferably provided for holding the bed in this as well as other of its rotated positions. As here shown, the bed and subframe are provided with a plurality of sleeve members 101 and 102 mounted for registration in different and selected rotated positions of the bed for receipt of a locking pin. The tru k is Y to the point of delivery of the first container. At such 4 position the subframe 18 and superimposed bed 13 and loaded tanks are elevated, as illustrated in Figure 3, thus raising particularly the rearwardly disposed tank 15. The legs 9194 of this tank are then lowered to the ground and fixed in their sleeves, as shown in Figure 3. Since the legs are individually adjustable in their sleeves, the tank may be set down on uneven terrain. After lowering and setting of the legs, the bed is lowered, thus effecting a relative elevation of tank 15 out of its saddle 82 and lowering the latter to a point where the truck may be driven forwardly out from under container 15 now supported on the ground by its legs 9194. The truck may then be driven to the point of delivery of the second tank 14. At such location, the turntable may be rotated as indicated in Figure 5, so as to position tank 14 rearmost. The bed may then be raised, legs on tank 14 dropped, the bed again lowered, and the truck driven out from under the tank in the manner described above in connection with the delivery of tank 15. At either of the delivery locations or elsewhere, the truck may be backed under an empty tank supported on its legs as illustrated in Figure 4, the bed elevated so as to engage the tank in the rearwardly disposed saddle 82, and the legs of the tank raised so as to support the tank on the bed.
Usually the tank to be delivered will be oriented at the rear of the truck by appropriate rotation of the bed, as above described, and in picking up a tank, the empty saddle 8182 is similarly positioned to the rear of the truck. Of course since the tanks and their ground engaging means are both sufficiently wide to completely straddle the truck, it is possible to deliver both tanks at the same time or to pick up two side by side tanks at the same time. It is also possible and desirable in many instances to either deliver or pick up tanks when oriented with their length other than perpendicular to the length of the vehicle. Such an arrangement is illustrated in Figure 6, in which it will be noted that the rearwardly disposed tank 15 and its ground engaging legs may be delivered from the truck with the tank turned to an oblique angle. In a similar but reverse operation, it will be understood that the truck may be run under a tank positioned at an oblique angle. It is also desirable in many instances to turn the tanks 14 and 15 with their axis parallel to the longitudinal axis of the truck. This is particularly so in cases where the truck may be run alongside of a loading dock 106, as illustrated in Figure 7, so as to arrange the tanks 14 and 15 parallel to the loading dock for removal of the tanks by means of a fork truck or other tank handling equipment. The truck turntable may be similarly positioned to receive tanks from a loading dock.
Preferably the chassis frame of the vehicle is provided with depending ground engaging means 107 which may be let down into engagement with the ground for stabilizing the support of the frame during loading and unloading of the containers, particularly in those instances where such loading or unloading operations are carried on with the containers at an oblique or off-center position, and to be elevated after such loading or unloading operations during the transportation of the load. As here shown, a pair of vertically adjustable leg members 108 and 109 are mounted at the opposite ends of a frame cross-member 111 secured to the rear ends 112 and 113 of the chassis rails 26 and 27. The legs are here mounted through sleeves 114 and secured in vertically adjusted position by pins 116 inserted through registerable openings in the sleeves and legs. Enlarged feet 117 and 118 are provided at the lower ends of the legs 108-109 for improved ground engagement and support.
